DETAILED DESCRIPTION

Hereinafter, exemplary embodiments will be described more fully withreference to the accompanying drawings. The inventive concept may,however, be embodied in many different forms and should not be construedas limited to the exemplary embodiments set forth herein. Rather, theseexemplary embodiments are provided so that this disclosure will bethorough and complete, and will fully convey the scope of the inventionto those skilled in the art. In drawings, elements irrelevant todescription are not shown for clear description, and like elementsdenote like reference numerals throughout the specification.

In the specification, when a region is “connected” to another region,the regions may not only be “directly connected”, but may also be“electrically connected” via another device therebetween. Also, when aregion “includes” an element, the region may further include anotherelement instead of excluding the other element, otherwise differentlystated.

FIG. 1 is a flowchart illustrating a process of displaying data on ascreen of a display apparatus according to a relative location of amobile terminal with respect to the display apparatus, by a displayapparatus, according to an exemplary embodiment.

The display apparatus 1100 performs short range wireless communicationwith the mobile terminal through a short range wireless communicationmodule included in the display apparatus, in operation S100.

According to an exemplary embodiment, the display apparatus may receiveinformation about the mobile terminal through the short range wirelesscommunication. Here, the display apparatus may include profileinformation about the mobile terminal, such as a type of the mobileterminal, a size of the mobile terminal, and a shape of the mobileterminal.

According to another exemplary embodiment the display apparatus mayreceive information about geomagnetism detected by a geomagnetic sensorincluded in the mobile terminal from the mobile terminal through shortrange wireless communication. The information about the geomagnetism maybe used to determine a direction where the mobile terminal is placed.

In the present specification, the direction of the mobile terminal isdetermined by using the geomagnetic sensor, but the geomagnetic sensormay be replaced by another sensor, such as a tilt sensor, to determinethe direction of the mobile terminal.

Then, the display apparatus may identify the short range wirelesscommunication module that performed the short range wirelesscommunication with the mobile terminal, from among a plurality of shortrange wireless communication modules, in operation S110.

According to an embodiment, an identification may be set for each of theshort range wireless communication modules. For example, identificationvalues N1, N2, N3, and N4 may be respectively set for four short rangewireless communication modules included in the display apparatus. Here,when an event of performing short range wireless communication with themobile terminal is generated in the short range wireless communicationmodule having the identification value of N2, the display apparatus mayobtain the identification value of N2. The display apparatus mayidentify the short range wireless communication module that performedthe short range wireless communication with the mobile terminalaccording to the obtained identification value.

Then, in operation S120, the display apparatus may determine a relativelocation of the mobile terminal with respect to the display apparatus,according to the result of identifying in operation S110.

According to an embodiment, a table for matching a coordinate valueindicating a location of the mobile terminal on the screen of thedisplay apparatus to the identification value of the short rangewireless communication module may be stored in the display apparatus.For example, coordinate values (x1, y1), (x1, y2), (x2, y1), and (x2,y2) may be matched respectively to the identification values N1 throughN4. When the display apparatus obtains the identification value N2 inoperation S110, the display apparatus may determine that the mobileterminal is located at a location corresponding to the coordinate value(x1, y2) on the screen of the display apparatus.

Also, according to an exemplary embodiment, the relative location maydenote the location of the mobile terminal on the screen of the displayapparatus. For example, when short range wireless communication modules1040 are arranged in a lattice shape on a rear portion of a screen 1300of a display apparatus 1100 as shown in FIG. 13, the mobile terminal1110 may be placed on the screen of the display apparatus 1100 so thatthe short range wireless communication module 1040 performs the shortrange wireless communication with the mobile terminal. Accordingly, thedisplay apparatus may identify the short range wireless communicationmodule that performed the short range wireless communication with themobile terminal to determine the location of the mobile terminal on thescreen of the display apparatus.

Alternatively, according to another exemplary embodiment, the relativelocation may denote the location of the mobile terminal within apredetermined range of a front portion of the display apparatus. Forexample, as shown in FIG. 18, when the short range wirelesscommunication modules 1040 are disposed on a front portion of thedisplay apparatus 1100, the mobile terminal may be placed within apredetermined range of the front portion of the display apparatus 1100so that the short range wireless communication module 1040 performsshort range wireless communication with the mobile terminal.Accordingly, the display apparatus may identify the short range wirelesscommunication module that performed the short range wirelesscommunication with the mobile terminal to determine the location of themobile terminal on the screen of the display apparatus.

Alternatively, according to another exemplary embodiment, the displayapparatus may compare information about geomagnetism that is detected bya geomagnetic sensor included in the mobile terminal and received fromthe mobile terminal, and information about geomagnetism detected by ageomagnetic sensor included in the display apparatus. The displayapparatus may determine the direction of the mobile terminal placed onthe screen of the display apparatus according to the result ofcomparing.

FIGS. 13 and 18 are only exemplary embodiments, and the inventiveconcept is not limited to structures shown in FIGS. 13 and 18.

Then, in operation S130, the display apparatus may display dataaccording to the relative location of the mobile terminal determined inoperation S120.

Here, the data may be data transmitted from the mobile terminal or datastored in a data storage unit of the display apparatus. In addition, thedata may include information to be displayed on the display apparatus orthe mobile terminal. For example, a photograph, a moving image, adocument, or a web page may be included in the data to be displayed onthe display apparatus.

According to an embodiment, the display apparatus may receive datathrough the short range wireless communication from the mobile terminal.For example, uniform resource locator (URL) information may be receivedthrough the short range wireless communication from the mobile terminal,and a web page may be displayed by using the received URL information.

According to another embodiment, the display apparatus may connect tothe mobile terminal by using a wireless communication method other thanthe short range wireless communication. Then, the display apparatus mayreceive data from the mobile terminal by using the other wirelesscommunication method. For example, a sub-system identification (SSID)and a password for an access point connected to the display apparatusmay be transmitted to the mobile terminal via the short range wirelesscommunication, and the mobile terminal may connect to the access point.The display apparatus may connect to the mobile terminal through theaccess point. Here, the access point may be included in the displayapparatus.

According to an exemplary embodiment, the display apparatus may displaythe data while further considering information about the mobile terminalin operation S130. For example, the data may be displayed at a locationon the screen away from the relative location by a predetermineddistance while further considering a size of the mobile terminal.

According to another exemplary embodiment, the display apparatus maydisplay data on the screen according to the direction of the mobileterminal determined in operation S130. For example, when thegeomagnetism detected by the mobile terminal and the display apparatusis tilted by 30°, the data may be displayed in a tilted state by 30° tothe right on the screen.
